HEATER.

SPECIFICATION forming part of Letters Patent No. l751,794, datedFebruary 9, 1904. Application led December 8, 1903. Serial No. 183,628.(No model.) L,

T (all 'wiz/07m it Wtfty concern:

Be it known that I, PETER J. VIHOAGLUND, a citizen of the United Statesof America, residing in Sterritt township, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Heaters, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inheaters, and more especially to that class of heaters in which the airis heated and discharged into the room or conveyed to other apartments.

The invention has for its object the provision of a heater particularlyadapted for use in connection with the burning' of natural gas as a fueland aims to provide for the rapid and economic heating of the air.

A further object of the invention is to pro- Y vide a heater in whichall of the fumes and non-combustible elements which arise from the flameare discharged into a flue, while the heated air is discharged into theroom or,

if desired, into separate ilues and conveyed to different apartments.

A practical form in which I have contemplated embodying my invention isillustrated in the accompanying' drawings and will be hereinafterdescribed in detail and then particularly claimed.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this application, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which Figure 1 is a vertical sectional elevation of a heaterconstructed in accordance with my invention. Fig. 2 is a horizontalsectional view taken on line 2 2 of Fig. 1. Fig. v3 is a like view takenon line 3 3 of Fig. 1. Fig. 4 is a like view taken on the line 4 4 ofFig. 1.

The body of the heater comprises a casing consisting of two members 1and 1', which herein shown is cylindrical in form, though it may be madeof other shape without departing from the spirit of the invention, thiscasing being mounted on a suitable base 2, which may be provided with anannular iiange 8 to hold the casing 1 in position on the base. 5o

The casing forming the body of the heater is provided adjacent its lowerend with a plurality of cold-air inlets 4 and has on its inner wallabove these cold-air inlets supportinglugs 5, on which rest the platemember 6, 55

which carries the central upwardly-extending pipe-section 7. The platemember is provided with a plurality of' openings 8,arrangedcircumferentially around the pipe-section 7, and

on its upper face the plate member 6 has an- 6o nular flanges 9,surrounding the openings 8. These annular flanges 9 receive the lowerends of vertically-disposed pipes or flues 10, that at their lower endsrest on the plate member G and which receive the cold air drawn inthrough in- 6 5 Alets 4, whereby to permit the same to be heated beforeit is discharged from the upper ends of pipes or flues l0. The pipes orflues 10 are provided with lugs 11 near their lower ends, or an annularflange would serve the same purpose, 7o

and which acts as a support for the burner-plate 12, provided withcircumferentially-arranged burner-openings 14 around each of the pipesor flues 10. Fitting on top of the upper edge of member 1 of the casinoVand on the u i )er 7" a D end of the pipe-section 7 is a partition-plate14', which receives'the lower edge of the upper member 1 of the casingand is provided adjacent its rim with an annular fiange 15 on both itsupper and lower faces to engage with 8o the inner Ywalls of the member 1and member l. This partition-plate, besides being provided with acentral opening to register with pipe-section 7, hascircumferentially-arranged openings 16, through which the pipes or ues 85 lO extend, and on its upper face this plate l4is provided with annularflanges 17 around each of the openings 16. These annular fianges receivethe lower ends of concentric pipes 18,

surrounding each of the pipes or fiues 10, the

annular space 19 between the inner walls of pipes 18 and exterior wallsof pipes 10 forming a fiue entirely surrounding the pipes 1() andthrough which the products of combustion and fumes are conducted to theflue 20.

The pipes 18 are received at their upper ends within the annular fianges2l, carried by the bottom plate 22 of the top casing, this top casingbeing provided with a concentrically-arranged pipe-section 28, and theupper plate 24 of this casing has an annular flange 25, that receivesthe upper ends of the pipes 10, the said top plate 24 having openings26, which register with said pipes. The concentricallyarranged pipes 18carry near their lower ends supporting-lugs 27, on which is supportedthe substantially inverted cone-shaped. deiector 28. A supply-pipe 29 isled into the space between plate 12 and plate 6 and is provided with amixer 30 of any desired or approved form. It is Aalso desirable undercertain conditions to admit air to the chamber between the plate 14 andplate 12, and to accomplish this end I provide the member 1 withopenings 31, controlling the amount of air admitted through saidopenings by means of a damper 32, of annular form, which is movable inclips 33, carried on the exterior of the member 1', and is provided withopenings 34, adapted to be brought into or moved out of registry withopenings 31. A suitable operating-handle 35 is provided for actuatingthis annular damper. The'gas is adapted to be ignited as it escapesthrough the openings 14, and the cold air drawn in through inlets 4 andpassing up through pipes 10 will be heated during its passage anddischarge at the upper end of the heater. The cold air which passes upthrough pipe-section 7 is deflected by member 28, so as to force thesame outwardly against the pipes 18. The products of combustion andfumes arising from the flame pass up through annular lues 19 and throughopening 17 into the bottom plate 22 of the top casing in the spacebetween plates 22 and 24 and to the iue 20.

In order that the gas escaping from each of the circular-arrangedburner-openings 14 may be ignited from the lighting of the gas at onepoint, I provide the burner-plate with openings 15 between each seriesof burner-openings 14.

Although the deflector 28 is shown as supported by pipes 18, it will beobserved that the same may be supported from the partitionplate 14. Thepurpose of this deflector is to cause the cold air that passes upthrough pipesection 7 to be diffused or spread outwardly around pipes 18in order that it may be more effectually heated. 'Ihe burner-openingsbeing around each pipe 10 the flame will impinge the said pipes and withthe pipes 18 at the lower portions oi' the latter.

In the practice of the invention it will be noted that various changesmay be made in the details of construction without departing from thegeneral spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a heater of the type described, an outer casing comprising anupper and lower member mounted one on top of the other, said lowermember provided with upper and lower rows of cold-air inlets, a platemember supported by the lower member of the casing and provided with anupwardly-extending pipe-section, said member havingcircumferentiallyarranged openings, pipes supported on said platemember, registering with said openings, a burner-plate supported on saidpipes, a partition-plate separating the upper and lower members of thecasing and provided with circumferentially-arranged openings, pipessupported on said partitionplate and inclosing the first-mentionedpipes, and a top casing comprising an upper and lower plate havingopenings registering with the respective pipes, substantially asdescribed.

2. A heater comprising an annular casing provided in its lower end withan upper and lower series of cold-air inlets, a damper controlling theupper series of said inlets, a plate member supported on the end of saidcasing and provided with circumferentially-arranged openings, a seriesof circumferentially arranged pipes supported on said plate member andregistering with the openings therein, a burner-plate supported by saidpipes within the casing above the plate member, a series of pipessupported by said partition-plate and through which the irst-mentionedpipes eX- tend, and a top casing having an upper and lower plateprovided' with openings registering with the respective pipes,substantially as described.

3. In a heater, a casing provided near its lower end with cold-airinlets and concentric-- ally-arranged pipes adapted to receive the air,a second series of pipes surrounding the lirstmentioned pipes, anair-deector supported by the second-mentioned pipes, and a top casingcomprising an upper and lower plate having openings registering with therespective pipes, substantially as described.

In testimony whereof I at'lix my signature in the presence of twowitnesses.
